Let's make it clear : I don't like dubstep. In fact, that's what I thought before listening this. It's a perfect mix between symphonical music and electronic sounds, and I found this awesome. Those music box sounds, accompanied with the "lyrics" (are those real words ? If yes, what does they mean ?) is genius, and even the dubstep part, that I dreaded, made finally a fantastic constrast with the symphonic part. Congratz !
